A necklace is a type of jewelry worn around the neck, typically made from a chain, cord, or band, and often adorned with decorative elements such as pendants, gemstones, beads, or charms. Necklaces come in a wide variety of styles, lengths, and materials, making them one of the most versatile and popular accessories in fashion.

The length of a necklace can vary greatly, with common types including chokers, which fit snugly around the neck; princess necklaces, which rest just below the collarbone; matinee necklaces, which typically reach the top of the bust; and opera necklaces, which are longer and often worn in a single strand or doubled for a layered look. There are also lariat necklaces, which are extremely long and can be wrapped or tied in various ways to create different styles.
